Embry-Riddle Aeronautical University (ERAU) team built a gas/electric hybrid aircraft, called EcoEagle, to enter the NASA-funded Green Flight Challenge in 2011. The battery system for EcoEagle consists of multiple battery modules in parallel. Each battery module has a fully functional battery management system (BMS), which is connected to a data bus controlled by a master controller. In this paper,...
Based on relationship marketing paradigm the trust mechanism of the impact of customer retention, trust are creatively divided into two dimensions of personal and enterprises, moreover it adds commercial friendship variable, then develops a structural equation model involving commercial friendship, trust of personal and enterprises and customer retention.

There are many remote airfields that are not connected to the power grid. Providing adequate lighting to these airfields is necessary and challenging. The Federal Aviation Administration (FAA) has sponsored a research project, Remote Airfield Lighting Systems (RALS), through the Center for General Aviation Research (CGAR). The findings from the RALS research specified a light that had low power needs...
After analyzing the existing problems of the current flameproof switchgear when realizing the complex protection actions, that is decaying DC component can not be filtered by using traditional full-cycle Fourier algorithm while decaying DC component disturbance effection works, and also the protection will fail to operate or unwanted operate. An improved Fourier algorithm is presented in this paper,...
